The invention is shown herein as employing in its structure certainparts of the heel-seat lasting machine disclosed in U. S. Letters PatentNo. 1,583,044, granted May 4, 1926 on an application of C. H. Hoyt. Theframe, shoe-supporting and shoe-positioning mechanism of that machineare satisfactory and serviceable for their intended function in thenovel machine herein disclosed. It will be understood that a machine ofdissimilar appearance might well result from modifying these parts,although such modification would not affect the characteristic featuresof the invention.

The head frame 10, supported at a convenient height by a column 11,comprises a portion which is substantially U-shaped and horizontallydisposed, opening toward the front of the machine, and an uprightportion in which is journaled the main operating shaft 34 of themachine. A jack 12 is mounted in the column 11 to swing from aforwardly-inclined shoe-receiving position into a substantially verticaloperative position as the shoe is presented to the machine. The jackcontains a spindle 13 which is free to turn and 'is arranged to belifted by treadle mechanism, not shown. The spindle 13 carries a toerest 14, a portion only of which is shown in Fig. 1, and is provided atits upper end with a head 15 having a transverse guide slot in its upperend. A carrier block 16 is mounted in the head 15 for free transverseadjusting movement and a last bed piece 17 is mounted in the carrierblock to tilt freely upon a transverse horizontal axis. The last bedpiece is preferably provided with a last pin and serves to support theinverted. last so that it may adjust itself and find a fair bearing whenthe heel-seat portion thereof is subjected to vertical pressure, as willpresently appear.

In various figures of the drawings is shown a lasted shoe in theposition which it occupies when presented to the machine. The upper 23is represented as having been conformed to the last and tacked about theheel-seat. The insole 21, with upwardly-extending ribs 22, lies upon thetread face of the last. The insole ribs may be formed in any commercialmanner and it will be understood that the particular type of insoleillustrated is selected only for purposes of illustration. The counter24 is interposed between the leather and lining parts of the upper 23.

The jack 12 is provided with rearwardly and upwardly-extending arms 25,to the upper end of which is pivotally connected a horizontallydisposedrack 26. A transverse rock shaft 27 is journaled in the column 11 andprovided with a pinion which meshes with the rack 26. A ratchet wheel 28is fast on the outer end of the shaft 27 and arranged to cooperate witha pawl mounted in an oscillatory carrier 29, journaled to swing on theshaft 27. The carrier 29 is connected through a link 30 to the lower endof a compound cam lever 31 journaled to rock upon the axis of astud 32projecting from the head frame 10. At its upper end the cam lever 31carries a cam roll which is operated by a cam 33 upon the main shaft 34of the machine.

At its rear end the shaft 34 is provided with a worm wheel 35 and this,in turn, meshes with a worm upon the transversely-disposed drive shaft36. The driving shaft 36 may be rotated from any convenient source ofpower and clutch mechanism is provided thereon which is arranged to betripped for starting the machine by a horizontal push rod having anoperating head 37. The details of the clutch mechanism are not I,

herein shown, beyond the stopping cam 127 and cam roll 130, as they formno part of the present invention.

Within the U-shaped opening of the frame 10 is provided heel-endclamping mechanism for accurately positioning and firmly holding theshoe during the operation of the machine. To receive and embrace theheel-end of the shoe, a flexible heel band 40 is supported at its rearend by a pair of spaced clips 41 carried at the ends of divergingadjustable arms 42. The arms 42 are mounted for limited verticalmovement on a post 43 which is carried at the forward end of a slide 44mounted in a guideway formed in the head frame and being adjustabletherein from front to rear. A horizontal shaft 45, withv gear teeth outin the inner end thereof, is arranged to mesh with rack teeth formed onthe lower face of the slide 44. The shaft 45 extends outwardly throughthe head frame 10 and is provided with an operating arm 46 withinconvenient reach of the operator. The arm 46 is associated with atoothed segment and provided with a spring detent by which it ismaintained in any position of adjustment. It will be understood that byrocking the arm 46 and turning the shaft 45, the slide 44 may be movedforwardly or rearwardly, thereby determining accurately the inner limityof movement of the lasted shoe when in operative position. A furthersupport for the rear end of the band is provided by a backing member 39which" is mounted upon or formed integral with the post 43.

The heel band 40 is of sufficient length to extend substantially to theshank of the lasted shoe.

swinging arms 49. To assist in pressing the band against thesides of theshoe in conformity to the counter thereof, the studs 48 carry blocks 56which have curved contact faces for engagement with the band. i

To assist in pressing the band inwardly against the contour of the endof the shoe, the arms 42 are arrangedto be engaged byspring plungers 54which are carried by arms 53 projecting forwardly in a divergent mannerfrom the slide 44; This construction permits the band to yield slightlywhen the shoe is forced rearwardly into operative position, so that theband is conformed accurately to the heel-end of the shoe.

For closing the band and forcing it inwardly against the sides of theheel-end portion of the shoe, the machine is provided with leverarms,not shown, which are connected tothe arms 49 to swing the latterinwardly. The connections comprise adjustable-links 52. These notonlycontract the sides of the band by a toggle action as the shoe is forcedinwardly but may be swung furtherinwardly by power, as fully disclosedin said Patent No. 1,583,044. It will be understood,

however, that, as in the machine of said Patent No. 1,583,044, the cycleof the machine is divided into two parts. After the jack is swungrearwardly by the operator. to present the shoe to thamachine andthemachine started, the cam lever 31 is rocked and'the jack pulledrearwardly to the limit of its movement by the pawl and ratchetmechanism already described. The jack spindle l3is also lifted by powerto subject the shoe always to a uniform degree of vertical pressuresuflicient to level the heel-seat thereon The heelband is at the sametime contracted firmly to engage and position the shoe and the formingor moldingtools, to be presently described, are brought into operation.The machine is then stopped with the shoe under pressure to give thestock time to settle itself under conforming pressure. Upon starting themachine for the second time, the parts are automatically returned totheir initial positions.

Above the Ushaped portion of the head frame 10 and bolted to'the forwardends'thereof'is a to the lower end of the post "63. The post 63is'provided with threads 64 and passes upwardly through aninternally-threadedworm wheel 65' which is confined in the block '61andacts as a' stationary nut for the threaded stem. The worm wheel 65 isarrangedto mesh with a horizontallydisposed, jointed Worm shaft 66 whichextends i outwardly from the casing 60 toward the righthand side of themachine, as shown in Fig. 4.

At its outer end, the worm shaft 66 has a geared connection, enclosed ina housing 68, with a-for-' weirdly-extending shaft provided with a handwheel 6'7 located within convenient reach of the relation to the formingtools, and in presenting the shoeto the machine the operator willelevate the jack spindle through its treadle connection-until furthermovement is arrested by contact of the cross bar 62 with the heel-seatof the shoe. This relation of the shoe and cross bar is shown in Figs; 5and '7.

The inside formers will now be described. The supporting block 61 isprovided with a pair of forwardly-extending trunnions or studs 70, uponeach of which is mounted a swing arm 71 forked at its upper end toembrace one of the studs '70. Each arm '71 is provided in its lower endwith a longitudinal bore in which is received an oscillating holder 72.Within the holder 72 is disposed the cylindrical stem of the insideformer 73, as shown in Figs. 4 and 7. The holder 72 is provided at itsinner end with longitudinally-extending teeth which mesh with circulargrooves 75 formed in an adjusting screw 74 having a knurled head forconvenience in turning. The adjusting screw 74 is also provided withthreads '76 which cooperate with internal threads in the arm 71. Theholder '72 is provided with an outwardlyextending pin '77 which passesthrough an outwardly flaring slot'78 in the arm 71 and engages theforked end of an indicator arm 79 pivotally mounted upon the front faceof each swing arm 71. A scale 80 upon the face of the arm cooperateswith the indicator arm. It will be apparent that by moving the adjustingscrew 74, the holder 72 may be oscillated in the arm 71 and that itsangular position will be indicated by the position of the indicator arm'79 on the scale 80. The adjustment discussed provides for the accurateangular positioning of the inside former 73 so that its effective facemay be brought into parallelism with the insole rib of the particularshoe being operated upon.

The stem of each insider former is provided with a key 82 which slidesina keyway in the wall.

of the holder '72, thereby permitting relative longitudinal movement ofthe two parts but maintaining them in a fixed angular relation. A compression spring 81 is interposed between the end of the stem of theformer 73 and the bottom of the holder 72 and this acts normally toprotrude the former 73. It is limited in its outward movement by aretaining plate 83 secured by screws to the arm 71 in the path of thekey 82 and this plate'isextended so that it serves also to retain theholder 72 in place. The two swing arms 71 are connected below the studs'70 by a tension spring 84 which tends always to swing them inwardly toa central initial position, in which they are in contact with each otherand with a projecting center web portion of the block 61, as shown inFig. 4. The swing arms are moved outwardly to carry the inside formers'73 into contact with the insole ribs by mechanism which will now bedescribed. 1

The block 61 is provided with a pair of vertical guideways formed inpart by gibs 94 and 95, best shown in Fig. 11, and retained in place bygib screws 96. In each of these guideways is mounted a rectangular slidehaving rack teeth cut in its inner face and a downwardly-extending stem91 to which is connected a hardened wedgeshaped cam block 92. The camblock 92 is removably connected to'the stem 91 and is backed up by theinner face of the guideway. In initial position, bothwedge blocks occupyan elevated position, as shown in Fig. 4, in close proximity to.-

the position shown in Fig. 4 to some such position as that shown inFig.- 7. To eliminate unnecessary friction in the face of each swing armis provided a rounded contact face 85 with which the face of the wedgeblock directly engages. At its upper end each slide 90 is provided withan upwardly-extending stem 93 and these are guided in vertical boresextending through the top' of the casing 60.

The block 61 is provided with a second pair of vertical'guidewayslocated parallel to and behind the guideways for the slides 90, and ineach of these second guideways is mounted a slide 97 having rack teethin its front face and an upwardlyextending stem 98 guided in a verticalbore extending through the top of the block imm diately behind the boresoccupied by the stems 93. A horizontal shaft 100 is journaledin-thecasing 60 and is providedwith a pair of separate drums 102, each havinga pinion 101 meshing with the rack teeth of one pair of slides 909'l, asshown in Figs. 10'and11. The result of this connection is to impartequal and opposite movementfrom the slide 97, which is acutatedto theslide 90, which operates one of the swing arms 71.

Each upwardly-extending stem 98 is provided with a forked head 99' whichis disposed above the top of the'casing 60. A pair ofv upwardly andrearwardly-extending brackets 108 are bolted to 1 the top of the casing60 and provide bearings for a stationary horizontal shaft 109. A pair ofbell crank levers are journaled upon the shaft 109. Each of these has aforwardly-extending arm 110 having a sliding block connection with thehead 99 of one of the actuating'slides 9'7 and a rearwardly-extendingsegmental arm 111 .slotted to receive a hardened segmental plate 112.The plates 112 are adjustably retained inplace by clamping screws 113and each is provided in its curved periphery with a notch having astraight front wall and a slightly beveled rear wall. A dog 114, shapedto fit this notch, is pivotally mounted at its forward end upon a stud115 disposed crosswise in a lever 116 mounted to swing upon the L shaft109 between the two bell crank levers 110 *111. The lever 116 isprovided at its upper end with a head 11'] in which areprovided-vertically arranged sockets for compression springs 118. Eachof the dogs 114 is provided with a boss 119 having a socket to receivethe lower endof one of the springs 118, and the head is provided with apair of adjusting screws 120 for regulating the compression of eachspring 113 and thereby the pressure of engagement of the dog 114 againstthe notched segment plate 112.

"'- end of a slide 125 which is mounted for vertical movement in waysformed in the: head frame. The slide 125 has a rearwardly-projecting camroll 126 which runs in the cam track of a cam disk 12"], fast on themain shaft 34 of the machine. The outline of the camtrack is shown inFig. 3,

from which it will be seen that in the stepped position of the machinethe slide 125 occupies a position at the upper limit of its stroke. Whenthe cam is rotated in'a counter-clockwise direction, as seen in Fig. 3;the slide 125 is-moved downwardly, and through the train of mechanismabove described the lever 116 is rocked rearwardly, the dogs beingmaintained in the notches of the segment plates 112 by the compressionsprings 118. Accordingly, the levers 110-111 are both rocked to lift theslides 97, rotating the pinions 101 and lowering the slides 90 with thewedge-shaped cam blocks 92, thereby separating and outwardly swingingthe arms '71 with the insideformers. When either former encounterstheinsole rib so that its movement is arrested, the dog 114 which isincluded in the train of mechanism operating that particular former willride out of the notch in the segment plate 112, lifting in opposition tothe compression spring 118. The former and its operating train ofmechanism back to and including the segment plate 112 is thus permittedto remain at rest while the dog 114 is free to complete its stroke,moving idly on the periphery of the segment plate. It will be understoodthat the formers 73 are each provided with a smooth plane outer facewhich is adapted to contact with the inner face of the insole rib,supporting it for an appreciable length over its entire area from rootto upper edge. The former is flanged laterally, as indicated at 86, forthe purpose of increasing its eifec tive length and the angle betweenits end or bottom'face and its rib-engaging face is somewhat less than aright angle to insure that the lower edge of the former may be fullybedded into the insole at the root of the rib. The operative position ofthe inside formers is well shown in Figs. 5 and '7 where these tools arerepresented as in the positions which they occupy when arrested bycontact with the insole ribs 22. The angular position of the formers ispreliminarily adjusted by turning the adjusting screws "14 so that theoperative face of each former coincides in angle and direction with thatof the insole rib. The wedge blocks 92 have been lowered variableamounts by the operating trains of mechanism actuated by the slide 125and the next step in the cycle of the machine is that of locking thewedge blocks 92. so that the inside formers will be rigidly supported towithstand molding pressure applied to the outer face of the insole ribs.

The locking mechanism for the wedge blocks 92 will now be described.Each of the drums 102 is provided at its outer end with an annularflange 136, this being received in a circular recess formed in thecasing 60 and closed by a cover plate 135b0lted to the casing. Arrangedconcentrically with respect to each annular flange 136 is an inner disk138 connected by a series of pins 139 with an outer disk 137, the latterbeing journaled in a recess formed in the inner face of the cover plate135. The disks 137 and 138 have also tongue and slot connection with asleeve 141 journaled upon the shaft 100. Each of the inner disks 138 isprovided with a rearwardly-extending arm 140 by which the cage, which isformed by the two disks, the sleeve 141 and the pins 139, may beoscillated for a purpose which will presently appear. A thick stationarydisk 142 fills the space within the annular flange 136 and hasperipheral pockets, each tapering toward one end and arranged to receiveone of the cross pins 139. The disk 142 may be termed the brake disk andis anchored by means of a series of flanged pins 143 which; project intothe body thereof fro-m the cover plate 135. The outer disks 137 areslotted where the pins 143 pass through them to permit the necessaryangular movement. A hardened clutch roller 144 is located in eachpocket. One

masses of the cross pins 1 39 passes through each of these pocketsbehind a roller 144 and a spring plunger 145 tends always to move theroller toward its pin 139 and toward the narrow end of the pocket. Whenthe roller is permitted to advance in the pocket, it becomes engagedbetween the inner face of the annular flange 136 and the bottom of itspocket in the brake disk 142, and the two are looked rigidly together,as in the well-known roller or Horton clutch.

The locking. mechanism is shown in Fig. 10 in initial position, whereinthe annular flange 136 is freeto rotate as the slides 90, are movedinadvancing the inside formers to operative position, and in this positionthe cage has been rocked.

by the arm 140 to force the spring plungers inwardly and hold therollers 144 in the wide portion of their pockets in the brake member.The arm 146 of each disk 138 is connected by a downwardly-extending link146 of adjustable length to one of two arrns 147 which extendsforwardlyfrom a rock shaft 148 journaled in bearings secured to a portion of theframe 10. At an intermediate point the rock shaft 148 is provided alsowith a rearwardly-extending arm 1.49 having a pin and slot connectionwith the lower end of an arm 151 projecting downwardly from a slide 156which is mounted in a vertical guideway in the upper portion of the headframe. The arm 151 is provided with a cam roll 152 running in a camtrack in the forward face of a cam disk 153 secured to the forward endof the cam shaft 34. As shown in Figs. 1 and 2, the slide occupiesinitially its lowermost position in the guideway. When the machine isset in operation and the shaft 34 has turned 45 or thereabouts, theslide 156 is raised, the rock shaft 148 rocked in a counter-clockwisedirection, and the arms 146 of each cage are swung downwardly, movingthe cross pins 139 to permit the rollers 144 to lock the annular flange136 rigidly to the static-nary brake disk 142. The drums162 are thus,held rigid and the wedge blocks 92 are locked so that the swing arms 71and the inside formers are held rigidly in position. 1 The insideformers are. maintained in locked position during something. over 200 ofthe machine cycle, and thereupon the slide 156 is lowered and the arms140 swung upwardly to their releasing position, as shown in Figs. 1 and10. I

The outside formers 160 which cooperate with the inside formers ineffecting the operation of molding the marginal upper material,including the counter, against the supported rib of the insole are eachprovided with an inwardly-extending molding flange 161 and are mountedfor angular adjusting movement so that the molding flange maybear fairlyand assume a position in which its efifective face is parallel to theface of the inside former. To this end, the body of each outside former160 is provided with a dove-tailed segmental portion 159 and this ismounted in an arcuate guideway formed in the head 162 of a slide 163,best shown in Fig. 6. Each inside former is, therefore, free to adjustitself about an axis which lies substantially in its effective face. Theadjusting movement of each former 160 is confined within suitable limitsby a stop plate 158 secured to the forward side of the head 162 and astop pin 157 which projects into the arcuate guideway in the head 162.

Each slide 163 is guided for horizontal movement toward and from theheel-seat of the shoe in the machine in guideways formed in the headframe 10. Each slide 163 is of a compound character, having an auxiliarysection 164 with an adjustable stop screw 165 threaded into its outerend which engages one end of a stiff compression spring 166 seated in-alongitudinal bore formed in the body of the slide 163. The auxiliarysection is provided in its rear face with rack teeth which mesh with apinion 167 rotatably mountedupon a vertical shaft 168 journaled in theframe 16. The pinion 167, in turn, meshes with a gear segment on theforwardly-extending arm of a bell crank lever 169 journaled on avertical stud 170. Each bell crank lever 169 has an inwardlyextendingarm having another gear segment thereon which meshes with rack teeth ina slide 156 which is guided. for movement fromfront to rear in aguideway formed in the head frame 10 but which is not shown in thepresent drawings. Ihe slide 156 is provided with a cam roll which runsin the cam track of a cam 154 on the shaft 34 and which is effective toreciprocate the slide forwardly and rearwardly at the proper time in themachine cycle. The slide 156 and its details of constructionv are morefully shown in my prior Patent No. 1,852,015, granted April 5, 1932, towhich reference may-be had. It will be understood from the foregoingdescription that the outside formers are moved inwardly under powerfulspring pressure and, on account of the compound character of the slide163 and the arrangement of the spring 166, they are brought to rest inpositions of pressure determined by the positions in which the insideformers have been previously locked.

The operation of the machine will be apparent from the foregoingdescription but for conven ience. may be summarized as follows. Thelasted shoe is jacked and swung rearwardly-by the operator into the heelclamp 40, which tightlyclamps the upper material to the sides ofthe lastabout the counter portion thereof. The final positioning movement of thejack is effected mechanically by the power of the machine both inrespect to its inward movement and to its upward movement, the latterbeing determined by the position of the leveling bar 62 which flattensand levels the heel-seat at the desired predetermined height. The slide125 is then lowered and, through its operating train, each inside formeris moved outwardly from the initial position shown in Fig. 4 to the.operative position shown in Fig. '7, in which the two insole ribs areengaged and supported in whatever position they may happen to be.Theslide 156 is thereupon raised and each inside former rigidly lockedin position of pressure. The horizontal slide 156 is thereupon advancedand the outside formers are moved inwardly, wiping over the marginalupper material, including the flange of the counter, and molding thisinto conformity to the shape of the face and rib of the insole. In thisoperation the A stiff counter material is leveled so that the lump whichwould otherwise occur at the point where the inseam should startisentirely eliminated. The machine is brought to rest with the parts inthe position shown in Fig. 7, when the projection 128 on the cam 127encounters thecam roll 130 of the stopping mechanism and the material tobe molded is thus heldunder molding pressure for an appreciable intervalof time. When this has elapsed, the machine is started for the secondtime in its cycle, whereupon the outside formers are retracted, thedrums 102 are unlocked, the Wedge blocks 92 are elevated, permitting thespring 84 to return the inside formers to initial position, and finallythe heel clamp is released,

allowing the shoe to be moved forwardly out of the machine.

In the foregoing discussion, emphasis has been laid upon the improvementmade in the condition of the shoe with reference particularly to theinseaming operation. This is an outstanding improvement resulting fromthe use of the machine but it will be appreciated that all thesubsequent shoemaking operations upon the heel-seat and shank of theshoe are facilitated and the results made more accurate and satisfactoryby the accurate shaping and molding of the marginal upper materialincluding the flange of the counter adjacent to the heel-breast line ofthe shoe. Ihe lines of the finished shoe are improved and its contour isbrought more accurately into conformity with the shape of the last. Forexample, the accuracy of the welt butting operation is improved and asmooth line may thus be secured at the juncture of the welt and outsole.These and similar benefits contribute to improve the quality of theshoemaking of shoes operated upon by the machine of my invention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
